LAMP-BURNER ATTACHMENT.

Specification of Letters Patent.

Patented Feb. 16, 1909.

To all whom it may concern:

Be it known that I, CLARENCE Z. Dnvrs, a citizen of the United States, and resident of Bufialo, in the county of Erie and State of 5 New York, have invented certain new and useful Improvements in Lamp-Burner Attachments, of which the following is a specification.

This invention relates to an attachment inafter described and claimed.

, In the drawings :Figure 1 is a perspec* tive view of a lamp burner having this attachment applied thereto; Fig. 2 is a side elevation of the said attachment; Fig. 3 is a J vertical section on the line 3-3 of Fig. 2;

and Fig. 4 is a perspective view of an attachment embodying this invention but of a modified form.

The attachment herein shown and described is preferably made of a single piece of metal, such as copper, whereby soldering is avoided and the softness and pliability of the material are such as to permit adjustment within the same range of the attachment to wick tubes of somewhat different dimensions. In the present instance the device is shown as made of a single sheet of metal requiring only bending to produce a complete and perfect attachment.

The device consists of two plates 1, 1 adapted to lie upon the top of a flat wick of a lamp, and to leave uncovered the central portion of said wick, but to cover the two end portions thereof, so that the center portion of sai wick may continue to feed flame, While flame from the two end portions is prevented. By test it has been found that if the ends of the wick over which the plates 1, 1, are lying are entirely inclosed the wick and wick tubes underneath the plates 1, 1 are carbonized by reason, it seems, of confinement of the heated petroleum or oil that is burned. It has also been found by test that if. a continuous surface of said wick is exposed above the wick tube running from said covered end portions to said uncovered end portion, the flame from the center portionwill extend under the plates and will burn on the side surfaces of said end portions,

and the result will be to create a feeding of oil to those end portions of the wick under said plates 1, 1, and therefore, on account of insuflicient flame under said plates, smoking from said end portions and odors will arise. But it has been found by thorough test that if the end portions of the wick underneath the plates 1, 1, are exposed to the air, and means are provided for preventing the flame from the center part of the wick passing around two said end portions, an odorless, non-smoking, reduced flame, corresponding to the area of the top edge of the wick. that is exposed between the plates 1, 1 is the re sult. In the present form of this invention, the said plates 1, 1 are formed integral with a folded plate 2 that iits around the wick tube 3 and has openings 4, 4 underneath and around the upper portions of the wick tube, but from said plate 2 there extend upward to the plates 1, 1 flanges 5, and 6, adjacent to the inner edges of the plates 1, 1, so that flame from the center portion of the wick cannot pass over said flanges or extensions 5 and 6. The lamp provided with this attachment will burn continuously and without odor or smoke, and with a flame reduced to correspond with the amount of the end of the wick that is covered by the plates 1, 1.

The wick 7 may be raised and lowered in the manner usual with lamps and the reduced flame will be adjusted in correspondence with such raising and lowering.

It is clear that the essentials of this attachment are a plate or plates for covering a portion of the wick, and plates extending downward therefrom to cover portions of the exposed sides of the wick to prevent flame from passing from the exposed upper edge of the wick across said downwardly extending portions. These downwardly extending portions may be enlarged into the form of plates surrounding the wick tube shown in the drawings.

In Fig. 4 is shown a modified form of the device in which the plates 8, 8 corresponding to the p1 ates 1, 1 have the downwardly extending portions 9, 9 at their ends to fit against the side edges of the wick tube, and the downwardly extending portions 10, 10, 11, 11, which fit against the sides of the wick tube and prevent the flame from passing from the middle of the wick underneath the plates 8, 8. The plates 11, 11 are attached by the plate 12 for convenience of manufacture and of fitting them upon the wick tube.

In both the forms shown the whole device A and bent into the form for actual use.

What I claim is 1. An inclosing cover for a lamp wick having an opening exposing a portion of the midd;e and covering the remainder of the top edge of the wick and the sides of the wick, and provided with openings exposing portions of the sides of the wick at the middle thereof and other portions adjacent to; the vertical end edges thereof.

2. An inclosing cover for a lamp wick having an opening exposing a. portion of the middle and covering the remainder of the top edge of the wick and the sides of the. wick, and provided with openings exposing tions of the. sides of the wick at, the mi die thereof and other portions adjacent to the vertical end edges thereof, and means for attaching said cover to a wick tube.

3. In a lamp burner attachment, a pair of horizontal pates having a space between.

thorn and adapted to rest. on the top edge. of a. wick: and to; expose a portion of the midcLe of said edge and to cover the remainder of said edge, two Vertical plates extending downwardly from each horizontal plate on each side of the Wick, and adjacent to said space and exposing the vertical edges and the adj acent portions of the sides of the wick.

4. In a lamp burner attachment, a pair of horizontal pates having a space between them and adapted to rest on the top edge 01' a wick and to expose a portion of the middle of said edge and to. cover the remainder ol'- said edge, two vertical plates extending downwardly from each horizontal plate on each side of the wick and adjacent to said space and exposing the vertical edges and the adjacent portions of the sides of the Wick, and a connection between two of the vertical plates on the same side of the wick and between the last mentioned plates and said horizontal plates.
